The THP-1000 electronic programmer is designed to perform
repetitive control functions such as CATV non-duplication switching
when a schedule is repeated on a weekly basis. The programmer operates
on the elapsed-time principal. This means that the stop and start
times of each event are programmed by the operator, rather than occurring
at arbitrary intervals as with pulse-time systems. This permits
programming the start and stop of each event to each selected minute
throughout the day.

Digital electronics are used in a unique manner in the 1MP-
1000 to provide the benefits of larger, more expensive programmers
that rely on dis~, core, or tape storage, while maintaining a price
competitive with the more limited pegboard programmers. Another important
advantage of this design is in the elimination of moving parts
which increases reliability.
